XigmaNAS is an open-source Network-attached storage (NAS) server software with a dedicated management web interface.

It includes ZFS v5000, Software RAID (0,1,5), disk encryption, S.M.A.R.T., and email reports etc., with the following protocols: SMB, Samba Active Directory Domain Controller AD, FTP, NFS, TFTP, AFP, rsync, Unison (file synchronizer), iSCSI (initiator and target), HAST, CARP, Bridge, UPnP, and BitTorrent.

[citation needed] XigmaNAS is installable on almost any boot medium including LiveCD, both for x86-64 and x86-32 computer platforms up to version 10.3.

[10] The preferred method is the embedded installation onto a USB stick, Compact Flash card (CF), or HDD/SSD, for which XigmaNAS was designed.

Flash devices are more energy efficient and the updating process can be done by WebGUI in the browser, downloading and installing a new firmware image.

With the support of the former developers, namely Daisuke Aoyama and Michael Zoon, it carries on the original FreeNAS code base.
